How to measure your cup size when shopping for a bra online

For ladies, knowing our “perfect fit” when it comes to intimate wear is a must. A small miscalculation can already result to either super loose or super tight inner-wear and that’s uncomfortable! With the changes due to the pandemic, we can no longer fit items at the mall, more so go out in fear of contracting the virus. The best alternative would be purchasing such items online, so here’s a quick guide that we learned from Avon while checking out their #LetHerBe campaign:

STEP 1: Find your BODY SIZE

To get the body size, place a measuring tape around your rib cage while wearing a bra. Stand straight, breathe normally, and make sure that your measuring tape is right under your bra line. Here are the body size measurements:

Underbust (CM)Body Size (IN)

STEP 2: Find your BUST SIZE

To find your bust size, maintain the same posture and wrap the measuring tape around the fullest part of your chest. That’s the bust size. You’ll need this info to compute for your cup size.

STEP 3: Get your CUP SIZE

The formula for this would be: BUST SIZE – BODY SIZE = CUP SIZE

STEP 4: Visit

No Avon lady in your area? No problem. When you head to, you only need to filter the options according to your cup size so you can check all available designs that you can choose from. This way, your products can be delivered straight to your doorstep and you can have less contact with other people.

Based on my experience, this method works as the products I’ve received from Avon were a perfect fit! The Louise Non-wire Bra I got is super comfortable for day-to-day use since I’m working from home anyway. The Eleanor Bra Underwire, on the other hand, is also comfortable despite having a wire since the lace in front lets my skin breathe. With the heat that we’re experiencing now, comfort must come first! The design is also really classy since they’re both lacy. Note, however, that such designs wouldn’t be recommendable if you’re wearing really tight tops, though!

I hope this guide will be able to help you as much as it helped me. After all, this is also part of #Adulting101s! I used to rely on try-ons before buying in sets, but due to the “new normal” that we’re in, online shopping is the best way to go. 🙂
